FIRE-PROOF CLOTH.

sPEcrFIcATIoN forming part ef Lettere Patent Ne. 290,238, dated December18, 1883.

Application led September 11,'1883. (No model.)

To all whom it may con/cern:

Be it known that I, 'HENRY W. JoHNs, of Stamford, Connecticut, have madea new and useful Improvement in Fire-Proof Cloth, of which thefollowingis such a full,clear, and exact description as will enable othersskilled in the art to make and use the same, when taken in connectionwith the accompanying drawings, in which- Figure 1 is a face view of thefabric; Figf2, a cross-section through the loose rolls or rope; Fig. 3,a cross-section of the same through the loose rolls or rope, showing thebindingthread. Fig. 4 is a longitudinal section of a modification of therope. Fig. 5 is a section of a modication.

This my invention is an improvement on the inventions set out inapplication No.

' 32,908, iiled by me on or about May 10, 1881,

and application filed by me at or about the date of filing thisapplication.

The invention consists in combining with fibrous asbestus a proportionof hair, so that the asbestus shall be thereby given greater' cohesion,be lighter in weight, and less eX- pensive than when pure fibrousasbestus is used for the purpose of making rolls or ropes, and combiningthem into cloths by weaving, sewing, or knitting them together, and informing such rolls or ropes on acord, string, or wire center, to give itadditional strength, whether the roll or rope be made of asbestus fiberand hair, or pure asbestus and the vavrious combinations hereinafterspecied.

For the purpose of carrying out this my invention, the asbestusis brokeninto fiber in the ordinary manner, and mixed with hair, preferably inthe proportion of twenty to fifty per cent. hair, and this mixedmaterial is rolled or twisted into rolls or rope-like structnres,- beingmade in a loose and compressible condition, so as to contain as muchairspace as possible. The roll or rope thus made -is woven, knitted, orsewed into a cloth, as described in the applications heretofore referredto. Through the center of the roll or rope thus made is placed a cord orwire, or the roll or rope is made about the cord or wire, so that it hasadded the strength of this cord or wire during the time ofitsmanufacture. and forms, with the other cords, threads, or wires withwhich it is woven, knitted, or sewed, a cloth. The advantages of thisform are that the cloth is stronger in the direction lengthwise of therolls or ropes, and is handled before completion with less danger ofbreaking.

I am aware that heretofore in making asbestus rope of several strands, astrand ofV helnp or other strong material has been inserted; but neverbefore this m'y invention was such a strand combined with a porous andcompressible cord or rope.

I am also aware that asbestus and hair have Ybeen mixed together andused as coverings for 2. The fabric hereinbefore described, cone sistingof a loose and compressible roll or rope surrounding a core of thread,cord, or wire woven, knit, or sewed with fine cord, thread, 'or wire,.as specified and set forth.
